given the atomic number,how would you know the number of electrons?
Answer: The atomic number represents the number of protons and the number of electrons. For example, if an element has an atomic number of 5, you can conclude it has 5 protons and 5 electrons.

See the answer above. Hope this helped! :)
Subject is Science: I need help plzzz!! If we have two different layers of water, one has a temperature of 70 degrees and one has a temperature of 30 degrees, which layer is going to be at the bottom? 30 degrees or 70 degrees?
Answer:
70 degrees water will be at the bottom. Ice floats, so it would make sense for the colder water to rise. Sorry if I'm wrong :>
Charles Darwin proposed the theory of evolution through the mechanism of natural
selection. In order for natural selection to occur, Darwin hypothesized that all

A.Lady beetles with fewer spots are more likely to survive.
B.Lady beetles with more spots are more likely to survive.
C.Lady beetles within a population may vary widely.
D.Lady beetles produce more offspring than can survive.

what are groups of reproducing populations that are isolated from other groups
Answer:
Species is a group of reproducing populations that are isolated from other groups.
Explanation:
Because animals and humans both create their own habitats!
When a trait is always expressed, it is considered to be a
trait.
O Recessive
O Codominant
O Dominant
O Incomplete
Answer:
O Dominant
Explanation:
An allele that is always expressed whenever it is present is called dominant. Mendel's law of segregation states that the two alleles for a trait segregate independently when gametes are formed.
Hope this helped!!!!!
A dominant trait is a form of trait which is ALWAYS expressed.

In a lake with three trophic levels (non-native fish, zooplankton, algae), an algal bloom occurs when the small population of zooplankton declines due to the predation of the invasive fish. Which of the following describes why zooplankton are the keystone species in this scenario?
Zooplankton are the smallest of all the herbivorous marine mammals in their communities.
The small population of zooplankton have an unequal effect on the marine community.
Marine mammals depend upon the work of zooplankton to convert sunlight into food.
Zooplankton help other populations survive by keeping out other herbivores.
Answers:
Zooplankton help other populations survive by keeping out other herbivores
Explanation:
This is because a keystone species are species that have large effect on the the habitat and through its effect they help to keep the ecosystem in existence. They make sure that the ecosystem exist. They help populations survive by keeping out herbivores and feeding on the algae. They help drive nutrients cycle and transfer energy from algae to invasive fish.

Answer:
B. The inner planets are closer to the sun
Explanation:
The inner planets are actually smaller than the outer planets, all of the planets have moons, otherwise they're not considered a planet, and the outer planets, since they are FARTHER away from the sun have increasingly larger orbits.
What are examples of things that can cause mutations?
Answer:
Exposure to chemicals.
Explanation:
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations. Hope this helped. :D

A park guide tells her that hoodoos like this one have been forming on Earth throughout history. Which principle explains the process that forms these rocks? A. erosion B. deposition C. weathering D. uniformitarianism
The principle that explains the process of forming hoodoos like this one is erosion. Therefore, option (A) is correct.
A hoodoo is a tall and thin rock formation characterized by a column of sedimentary rock that has been eroded over time, leaving a pinnacle or spire-like structure. Hoodoos are typically found in arid or semiarid areas with a high concentration of soft rock such as sandstone, limestone, or volcanic tuff. These formations are often created by a combination of factors such as water erosion, wind erosion, and frost weathering.
Hoodoos can take on various shapes and sizes and may be found singly or in groups, forming intricate and awe-inspiring landscapes. They are commonly found in national parks and other natural areas around the world, including the United States, Canada, China, and Australia, where they attract tourists and geology enthusiasts alike.

Use the model of meiosis that you made earlier in the lesson to explain how crossing over contributes to genetic diversity. How did you modify your model? How do you think crossing over affects the expression of certain traits compared to the cells where crossing over didn’t occur?
Answer:
Due to exchange of parts of chromosome.
Explanation:
Crossing over is the exchange of segments or parts of chromosome between non-sister chromatids in the meiosis cell division. Due to crossing over, new combinations of genes in the gametes are formed that are not found in both parent which leads to genetic diversity. Crossing over affects the expression of certain traits in the organism because the organism that crossing over have different features as compared to their parents so there is a big difference between organism have crossing over and no crossing over.

Explain how many ancient and medieval societies forwarded marine science even though they were not specifically addressing issues in marine science.
Answer:
Marine life is the study that investigates the plants and animals of the water environment; it is also known as " aquatic biology, " " water science, " And " life oceanography. " the better studies the marine plant and animal experience found in bays, harbors, wetlands, and other water and coastal regions.
Answer:
Many ancient and medieval societies advanced marine science through their exploration, trade, and navigation activities, even though they were not specifically addressing issues in marine science. For example, ancient seafaring civilizations such as the Phoenicians, Greeks, and Romans developed sophisticated navigation techniques, shipbuilding methods, and trade networks that required a deep understanding of the ocean's physical and biological processes. Similarly, medieval societies such as the Vikings and the Chinese developed advanced shipbuilding technologies and navigational instruments that allowed them to explore and trade across vast distances. These activities required knowledge of ocean currents, tides, and weather patterns, which contributed to the development of marine science as a field of study. Additionally, many ancient and medieval societies also recorded observations of marine life, ocean currents, and weather patterns, which provided valuable insights into the ocean's physical and biological processes and helped to advance marine science.
